PREFACE

This yearbook is planned to include accounts of what is actually being done in secondary agricultural education in various parts of the United States. The program represents an analysis of the typical experiments that are being undertaken, with some interpretation of each plan and its results. The contributors of the articles are specialists who are in intimate touch with the special phases of the work which they describe. To these men the National Society is indebted for their assistance and co-operation. The editor desires to express his special appreciation of the assistance of Mr. D. J. Crosby, of the United States Department of Agriculture, who organized the program and upon the urgent invitation of the editor agreed to prepare the third paper of the volume.
